Hi comy,

You also need to add libm.a in the linker path.

Add "${ARMGCC_INSTALL_PATH}\arm-none-eabi\lib\libm.a" as shown in the attached figure.

Thanks,

sai krishna.

Comy,

Could you please check whether you have libm.a in the path SDK\1.2\\arm-none-eabi\lib\

If you don't have please place the attached libm.a there.

In my PC, I have that library file in the following path:

C:\Program Files\Cypress\ARM GCC\arm-none-eabi\lib

Thanks,

sai krishna.

Hi,

I observed a similar issue...
The path to the lib is somehow damaged!
In your error-message...

"arm-none-eabi-gcc: SDK\1.2\\arm-none-eabi\lib\libm.a -mcpu=arm926ej-s -mthumb-interwork -g -gdwarf-2 -oUSBBulkLoopManual.elf: No such file or directory."

... there is missing the install-path of the Cypress-SDK, something like "C:\Cypress\"!!!

You should check the content of the path-variable FX3_INSTALL_PATH which you can find in the system-properties of your PC => environment-variables!

In my case the variable was even ok and I just could solve this issue by checking out my project again from our SVN-repository!

Seems to be a problem/bug in Eclipse...?!

So maybe you should delete the example project in Eclipse and import it again.

 

Regards,

Robert

Oh, I just saw that you need an gcc-lib!

Then you have to check the content of the variable ARMGCC_INSTALL_PATH instead of FX3_INSTALL_PATH, of course!
